Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a machine tool cutting fluid purification treatment device. Background Art

[0002] Cutting fluid is an industrial cutting fluid used in metal cutting and grinding processes to cool and lubricate tools and workpieces. Metal or non-metallic powder impurities and lubricating oil substances such as butter and engine oil generated during the mechanical processing will fall into the cutting fluid, which will form a large amount of floating oil and powder on the surface of the cutting fluid. The continuous accumulation of the above-mentioned floating oil and powder impurities on the cutting fluid and the hot and humid processing environment can easily cause a large number of microorganisms to breed in the cutting fluid, which in turn causes the cutting fluid to deteriorate and produce an unpleasant odor. In this case, if the cutting fluid continues to be recycled, the erosion of the powder and microorganisms in these cutting fluids will lead to a decline in the processing quality of the workpiece, and even cause the workpiece and machine tool to rust. Frequent replacement of the cutting fluid takes a lot of time, thereby reducing work efficiency.

[0003] At present, most of the existing technologies use filter elements to purify the cutting fluid. This method uses a layer-by-layer filtration method to filter out impurities and some miscellaneous oils in the cutting fluid. Its filtration efficiency is low, and the requirements for filtration materials are high, and the cost of use remains high. There is also a high-speed centrifugal method that uses the principle that impurities, oil and cutting fluid have different densities and masses. High-speed centrifugal purification equipment is used to separate three substances with different specific gravities. Not only is the power consumption high, but the effective components in the cutting fluid will also be separated during the high-speed centrifugal operation, making the cutting fluid ineffective.
